The ability to evolve may well be part of the design.
Except that the flesh body was by design to house the soul/spirit intellect, that was created long before this flesh age. All souls/spirit intellect were created at the same time. Each that will, gets their opportunity to take this flesh journey. First requirement to 'see' the kingdom of God. Conservatism is individual personal responsibility and so it shall be how judgment occurs.
That's like saying static is designed into radios.
“Design vs. evolution is a fallacy of false dichotomy.
The ability to evolve may well be part of the design. “
Absolutely true.
But design vs evolution refers specifically to intelligent design wherein, I think, both ID’ers and Darwinists agree there is a dichotomy.
AFAIK, there is only evidence of speciation, e.g. dog breeds, "Darwin's finches", etc.
There is no evidence for variation outside the the Biblical "kinds", which might very well be the taxonomic classification of family.
